fcl-json - is JSON (Javascript Object Notation) implementation
Notes
Contains the fpjson JSON manipulation unit.
Note: In FPJSON, accessing e.g. SomeJSONObject.Integers['price'] may give a SIGSEGV/Access Violation if that integer variable does not exist. This is apparently intentional, see [1] You'd hav to use the .Find method (not available in FPC 2.6.0) to first check if the element/variable (price in this example) exists.
